[B].m2ts[/B] files can be very large in size between the number of folders and video files. This setting allows you to ignore them in your cloud storage. This should result in a speed increase should they exist and you chose to ignore them. Note: if you do not keep .m2ts files in your cloud this setting will have no effect. If you choose to keep and view them the performance hit per debrid provider varies. AD and PM is very slight while RD seems to take the biggest hit at 1-2second increase in scrape time.
